PDO Threads
PDO Threads are hypodermic needles preloaded with an absorable PDO suture.
PDO (Polydioxanone) is a synthetic absorable surgical suture composed of polydioxanone. Your skin will fully absorb it within 4-6 months and will not leave you with any scar tissue.
Restoring the V-shape
The idea with PDO threads is to create a scaffolding in order to support the tissues and keep them in the V-shape or where necessary to deliciately lift the tissues and reposition the skin to recreate the V-shape where it's been lost.
